VALVE FOR AIR STARTER SYSTEMS.

vide an improved valve structure for controlling the admission of compressed air to the engine cylinder.

, Another object is the provision of valve actuating means by which the valve may be manually opened for a brief period to admit suificient'air to the cylinder to carry the crank shaft of the engine for a half revolution.

Another object is the provision of a valve structure of this character in which the valve is automatically returned to closed sition subsequent to an operation thereo to automaticallycut off the supply of air to the engine cylinder.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, accompanied by elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claims appended hereto.

Figure 1 represents a fragmental side elevation of a conventional type of explosive engine illustrating the invention applied to use,

Fig. 2 represents a longitudinal sectional vicar through the valve, partly broken away, an

- Fig. 3 represents a detail elevation of the controlling device for the valve.

, Referring to the drawing in detail, wherein. similar reference characters designate corresponding parts throughout the several views the numeral 5 indicates a substantially T-shaped valve casing the head portion 6 of which is formed with alined inlet and outlet ports 7 and 8, respectively, the former being Specification of Letters Patent.

adapted to receive an air supply pipe 9 adapted for connection with a reservoir in which is stored compressed air under adequate pressure to actuate the piston therein and impart an initial rotary movement to the crank shaft.

The stem 10 of the valve casing is formed throughout a portion of its bore with internal screw threads receiving a plug 11 constituting a guide for the valve stem 12 and the terminal of the plug is formed with a recess disposed concentric with the bore and receiving a preferred type of packing element 13 held in place by cap nut 14: to prevent leakage of air about the stem. The inner terminal of the stem is pivotally secured at 15 between integral bifurcations 16 carried by a slide valve 17 which latter is movable over the plane face or seat 18 formed by one side of a vertical partition 19 formed internally of the head 6 and adjacent the outlet port 8. An expansion spring 20 1s confined between the plug 11 and a collar or rlng 21 secured to or formed integral with the stem 12 and the tension of which normally tends to elevate and close the valve 17 over the diagonal port 22 through the seat or partition 19.

The outlet terminal of the port 8 is formed with exterior screw threads 23 whereby the valve casing is secured in the head of an explosive engine cylinder 24:, as suggested in Fig 1, and is provided internally with threads receiving a sleeve 25 provided with internal side arms 26 supporting a guide 27 in which is slidably mounted the stem 28 of the valve 29. A nut 30 is fitted upon the terminal of the stem 28 and constitutes an abutment for one terminal of a spring 31 the opposite end of which is engaged by the guide 27 and normally retains the valve 29 in engagement with its seat 32 provided at the beveled edge of the sleeve 25. y

A disk 33 is mounted upon a support 34' attached to the base of the engine 2 1 and is provided with a substantially semicircular flange 35 one terminal of which is beveled as at 36 for engagen'ient with the pivoted latch 37. A laterally projecting pin 38 is formed upon the disk 33 at a point adjaorder that the length of the latch member 37 may be varied to adapt the device to various types on engines, the latch is separately constructed in two sections connected'by a screw 42. s
